1 FUNCTIONAL DESCRIPTION
1.1 FM Section
1.2 Mixer1, AGC and 1.IF
Mixer1 is a wide dynamic range stage with low noise and large input signal performance. The mixer1 tank canbe adjusted by software (IF1T). The AGC operates on different sensitivities and bandwidths (FMAGC) in orderto improve the input sensitivity and dynamic range (keying AGC). The output signals of AGC are controlled volt-age and current for preamplifier and prestage pin diode attenuator. (look at Figure 4)
Two 10.7MHz programmable amplifiers (IFG1, IFG2) correct the IF ceramic insertion loss and the costumer lev-el plan application.
1.3 Mixer2, Limiter and Demodulator
In this 2. mixer stage the first 10.7MHz IF is converted into the second 450kHz IF. A multi-stage limiter generatessignals for the complete integrated demodulator without external tank. MPX output DC offset compensation ispossible by software (DEM).
1.4 Quality Detection and ISS (look at Figure 2)
Fieldstrength
Parallel to mixer2 input a 10.7MHz limiter generates a signal for digital IF counter and a fieldstrength output sig-nal. This internal unweighted fieldstrength is used for keying AGC, adjacent channel and multipath detectionand is available at PIN14 (FSU) after +6dB buffer stage. The behaviour of this output signal can be correctedfor DC offset (SL) and slope (SMSL). The internal generated unweighted fieldstrength is filtered at PIN35 andused for softmute function and generation of ISS filter switching signal for weak input level (sm).
Adjacent Channel Detector
The input of the adjacent channel detector is AC coupled from internal unweighted fieldstrength. A programma-ble highpass or bandpass (ACF) and amplifier (ACG) as well as rectifier determines the influences. This voltageis compared with adjustable comparator1 thresholds (ACWTH, ACNTH). The output signal of this comparatorgenerates a DC level at PIN15 by programmable time constant. Time control (TISS) for a present adjacent chan-nel is made by charge and discharge current after comparator1 in an external capacitance. The charge currentis fixed and the discharge current is controlled by I2C Bus. This level produces digital signals (ac, ac+) in anadditional comparator4. The adjacent channel information is available as analog output signal after rectifier and+8dB output buffer.
Multipath Detector
The input of the multipath detector is AC coupled from internal unweighted fieldstrength. A programmable band-pass (MPF) and amplifier (MPG) as well as rectifier determines the influences. This voltage is compared withan adjustable comparator2 thresholds (MPTH). The output signal of this comparator2 is used for the "Milano"effect. In this case the adjacent channel detection is switched off. The "Milano" effect is selectable by I2C Bus(MPOFF). The multipath information is available as analog output signal after rectifier and +8dB output buffer.
450kHz IF Narrow Bandpass Filter (ISS filter)
The device gets an additional second IF narrow bandpass filter for suppression noise and adjacent channel sig-nal influences. This narrow filter has three switchable bandwidthes, narrow range of 80kHz, mid range of120kHz and 30KHz for weather band information. Without ISS filter the IF bandwidth (wide range) is definedonly by ceramic filter chain. The filter is switched in after mixer2 before 450kHz limiter stage. The centre fre-quency and matching to the demodulator center frequency can be fine adjusted (AISS) by software..
Deviation Detector
In order to avoid distortion in audio output signal the narrow ISS filter is switched OFF for present overdeviation.

Hence the demodulator output signal is detected. A lowpass filtering and peak rectifier generates a signal thatis defined by software controlled current (TDEV) in an external capacitance. This value is compared with a pro-grammable comparator3 thresholds (DWTH, DTH) and generates two digital signals (dev, dev+).
ISS Switch Logic
All digital signals coming from adjacent channel detector, deviation detector and softmute are acting via switch-ing matrix on ISS filter switch. The IF bandpass switch mode is controlled by software (ISSON, ISS30, ISS80,ISSCTL). The switch ON of the IF bandpass is also available by manipulation of the voltage at PIN15. Two ap-plication modes are available (APPM). The conditions are described in table 37.
1.5 Soft Mute Control
The external fieldstrength signal at PIN 35 is the reference for mute control. The startpoint, mute depth and slopeare programmable (SMTH, SMD, SLOPE) in a wide range. The time constant is defined by external capacitance.Additional adjacent channel mute function is supported. A highpass filter with -3dB threshold frequency of100kHz, amplifier and peak rectifier generates an adjacent noise signal from MPX output with the same time con-stant for softmute. This value is compared with comparator5 thresholds (ACM). For present strong adjacent chan-nel the MPX signal is attenuated typical 6dB.
1.6 AM Section
The upconversion mixer1 is combined with a gain control circuit 1 sensing three input signals, narrow band in-formation at PIN 39, upconversion signal at PIN 58 and wide band information at PIN 3.This gain control circuitgives two output signals. The first one is a current for pin diode attenuator and the second one is a voltage forpreamplifier. It is possible to put in a separate narrow bandpass filter before mixer2 at PIN 58. The interventionpoint for first AGC (AMAGC) is programmable by software.
The oscillator frequency for mixer1 is generated by dividing the FM VCO frequency (AMD).In mixer2 the IF1 is downconverted into the IF2 450kHz. Before the output signal reaches the 450kHz tank anattenuator for IF gain control 2 is passed. Mixer1 and mixer2 tanks are software controlled adjustable (IF1T, IF2T).
After filtering by ceramic filter a 450kHz amplifier with a gain control 3 is included. The gain control 2 and 3 arethe second AGC and programmable too by software (DAGC). In order to avoid an oscillation in intervention pointit is important to know that the DAGC threshold has to be smaller than AMAGC! .
The demodulator is a peak detector. A further time constant with capacitor at pin40 produces a DC AGC refer-ence voltage dependent on input signal. The time constant is switchable by ratio of 30. This is necessary for thestation search function. The switching is software controlled (AMSEEK).
An internal comparator compares the AGC voltage with a programmable reference (AMSS). Consequently it ispossible to generate a seekstop impulse over a defined range.A separate output is available for AMIF stereo or a permanent seek stop signal(SSTSEL).
1.7 PLL and IF Counter Section
PLL Frequency Synthesizer Block
This part contains a frequency synthesizer and a loop filter for the radio tuning system. Only one VCO is requiredto build a complete PLL system for FM and AM upconversion. For auto search stop operation an IF countersystem is available.
The counter works in a two stages configuration. The first stage is a swallow counter with a two modulus (32/33)precounter. The second stage is an 11-bit programmable counter.The circuit receives the scaling factors for the programmable counters and the values of the reference frequen-cies via an I2C-Bus interface.The reference frequency is generated by an adjustable internal (XTAL) oscillatorfollowed by the reference divider. The reference and step-frequencies are free selectable (RC, PC).
Output signals of the phase detector are switching the programmable current sources. The loop filter integrates

their currents to a DC voltage.
The values of the current sources are programmable by 6 bits also received via the I2C Bus (A, B, CURRH, LPF).
To minimize the noise induced by the digital part of the system, a special guard area is implemented.
The loop gain can be set for different conditions by setting the current values of the chargepump generator.
Frequency Generation for Phase Comparison
The RF signals applies a two modulus counter (32/33) pre-scaler, which is controlled by a 5-bit divider(A). The5-bit register (PC0 to PC4) controls this divider. In parallel the output of the prescaler connects to an 11-bit di-vider(B). The 11-bit PC register (PC5 to PC15) controls this divider
Dividing range:
fOSC = (R+1) x fREF
fVCO = [33 x A + (B + 1 - A) x 32] x fREF
fVCO = (32 x B + A + 32) x fREF
Important: For correct operation: A ≤ 32; B ≥ A
Three State Phase Comparator
The phase comparator generates a phase error signal according to phase difference between fSYN and fREF.This phase error signal drives the charge pump current generator.
Charge Pump Current Generator
This system generators signed pulses of current. The phase error signal decides the duration and polarity ofthose pulses. The current absolute values are programmable by A register for high current and B register forlow current.
Inlock Detector
Switching the chargepump in low current mode can be done either via software or automatically by the inlockdetector, by setting bit LDENA to "1".
After reaching a phase difference of 10 - 40nsec and a delay of some times 1/fREF, the chargepump is forcedin low current mode. A new PLL divider alternation by I2C-Bus will switch the chargepump in the high currentmode.Few programmable phase errors (D0, D1) are available for inlock detection
The count of detected inlock informations, to release the inlock signal is adjustable (D2, D3), to avoid a switchingto low current during a frequency jump.
Low Noise CMOS Op-amp
An internal voltage divider at pin VREF2 connects the positive input of the low noise op-amp. The charge pumpoutput connects the negative input. This internal amplifier in cooperation with external components can providean active filter. The negative input is switchable to three input pins, to increase the flexibility in application. Thisfeature allows two separate active filters for different applications.
A logical "0" in the LPF register activates PIN LPFM, otherwise PIN LPAM is active. While the high current modeis activated LPHC is switched on.
IF Counter Block
The input signal for FM and AM upconversion is the same 10.7MHz IF level after limiter. The grade of integrationis adjustable by eight different measuring cycle times. The tolerance of the accepted count value is adjustable,to reach an optimum compromise for search speed and precision of the evaluation.
For the FM range the center frequency of the measured count value is adjustable in 32 steps, to get the possi-bility of fitting the IF-filter tolerance. In the AM upconversion range an IF frequency of 10.689MHz to 10.720MHzwith 1kHz steps is available.

The IF-Counter Mode
The IF counter works in 2 modes controlled by IFCM register.
Sampling Timer
A sampling timer to generate the gate signal for the main counter is build with a 14-bit programmable counter(IRC). In FM mode a 6.25kHz, in AM mode a 1kHz basically signal is generated. This is followed by an asyn-chronous divider to generate several sampling times.
Intermediate Frequency Main Counter
This counter is a 11 - 21-bit synchronous autoreload down counter. Five bits (CF) are programmable to havethe possibility for an adjust to the frequency of the IF-filter. The counter length is automatic adjusted to the cho-sen sampling time and the counter mode (FM, AM-UPC).
At the start the counter will be loaded with a defined value which is an equivalent to the divider value(tSample x fIF).
If a correct frequency is applied to the IF counter frequency input at the end of the sampling time the maincounter is changing its state from 0h to 1FFFFFh.
This is detected by a control logic and an external search stop output is changing from LOW to HIGH. The fre-quency range inside which a successful count result is adjustable by the EW bits.
tTIM = (IRC + 1) / fOSC
tCNT = (CF + 1697) / fIF FM mode
tCNT = (CF + 10689) / fIF AM up conversion mode
Counter result succeeded:
tTIM ≥ tCNT - tERR
tTIM ≤ tCNT + tERR
Counter result failed:
tTIM > tCNT + tERR
tTIM < tCNT - tERR
tTIM = IF timer cycle time
tCNT = IF counter cycle time
tERR = discrimination window (controlled by the EW registers)
The IF counter is only started by inlock information from the PLL part. It is enabled by software (IFENA).
Adjustment of the Measurement Sequence Time
The precision of the measurements is adjustable by controlling the discrimination window. This is adjustable byprogramming the control registers EW0 to EW2.
The measurement time per cycle is adjustable by setting the Register IFS0 - IFS2.
Adjust of the Frequency Value
The center frequency of the discrimination window is adjustable by the control register CF0 to CF4.

1.8 I2C-Bus Interface
The TDA 7511 supports the I2C-Bus protocol. This protocol defines any device that sends data onto the bus asa transmitter, and the receiving device as the receiver. The device that controls the transfer is a master anddevice being controlled is the slave. The master will always initiate data transfer and provide the clock to trans-mit or receive operations.
Data Transition
Data transition on the SDA line must only occur when the clock SCL is LOW. SDA transitions while SCL is HIGHwill be interpreted as START or STOP condition.
Start Condition
A start condition is defined by a HIGH to LOW transition of the SDA line while SCL is at a stable HIGH level.This "START" condition must precede any command and initiate a data transfer onto the bus. The TDA 7511continuously monitors the SDA and SCL lines for a valid START and will not response to any command if thiscondition has not been met.
Stop Condition
A STOP condition is defined by a LOW to HIGH transition of the SDA while the SCL line is at a stable HIGHlevel. This condition terminates the communication between the devices and forces the bus-interface of the TDA7511 into the initial condition.
Acknowledge
Indicates a successful data transfer. The transmitter will release the bus after sending 8 bits of data. During the9th clock cycle the receiver will pull the SDA line to LOW level to indicate it receive the eight bits of data.
Data Transfer
During data transfer the TDA 7511 samples the SDA line on the leading edge of the SCL clock. Therefore, forproper device operation the SDA line must be stable during the SCL LOW to HIGH transition.
Device Addressing
To start the communication between two devices, the bus master must initiate a start instruction sequence, fol-lowed by an eight bit word corresponding to the address of the device it is addressing.
The most significant 6 bits of the slave address are the device type identifier.
The TDA 7511 device type is fixed as "110001".
The next significant bit is used to address a particular device of the previous defined type connected to the bus.
The state of the hardwired PIN 41 defines the state of this address bit. So up to two devices could be connectedon the same bus. When PIN 41 is connected to VCC2 the address bit “1” is selected. In this case the AM partdoesn’t work. Otherwise the address bit “0” is selected (FM and AM is working). Therefor a double FM tunerconcept is possible.
The last bit of the start instruction defines the type of operation to be performed:
- When set to "1", a read operation is selected
- When set to "0", a write operation is selected
The TDA 7511 connected to the bus will compare their own hardwired address with the slave address beingtransmitted, after detecting a START condition. After this comparison, the TDA 7511 will generate an "acknowl-edge" on the SDA line and will do either a read or a write operation according to the state of R/W bit.

TDA7511
Write Operation
Following a START condition the master sends a slave address word with the R/W bit set to "0". The TDA 7511will generate an "acknowledge" after this first transmission and will wait for a second word (the word addressfield). This 8-bit address field provides an access to any of the 32 internal addresses. Upon receipt of the wordaddress the TDA 7511 slave device will respond with an "acknowledge". At this time, all the following wordstransmitted to the TDA 7511 will be considered as Data. The internal address will be automatically incremented.After each word receipt the TDA 7511 will answer with an "acknowledge".
Read Operation
IF the master sends a slave address word with the R/W bit set to "1", the TDA 7511 will transit one 8-bit dataword. This data word includes the following informations:
bit0 (ISS filter, 1 = ON, 0 = OFF)
bit1 (ISS filter bandwidth, 1 = 80kHz, 0 = 120kHz)
bit2 (MPOUT,1 = multipath present, 0 = no multipath)
bit3 (1 = PLL is locked in , 0 = PLL is locked out).
bit4 (fieldstrength indicator, 1 = lower as softmute threshold, 0 = higher as softmute threshold)bit5 (adjacent channel indicator, 1 = adjacent channel present, 0 = no adjacent channel)
bit6 (deviation indicator, 1 = strong overdeviation present, 0 = no strong overdeviation)
bit7 (deviation indicator, 1 = overdeviation present, 0 = no overdeviation)
